Hi, I dont know how neccesary eye protection is. Your gonna get injuries if you train hard, I think its a fact of life. There was one guy who wore goggles over his glasses and he was nick named ''eddie the eagle'', he didnt mind.
You could say you need anal protection, cause a few times weve had uke's arse hole land on the end of the tip of a bokken. He was of for session but was back in action the next day. Hope it doesnt happen to me.
